Application flied May 20, 189s. senti No. 474,950. (No model.)

To all whom it may concern,.-

Be it known that I, BENJAMIN FRANKLIN STONE, a citizen of the UnitedStates, residing at Las Vegas, in the county of San Miguel and Territoryof New Mexico, have invented a new and useful Pipe-Coupling, of whichthe following is a specilication.

This invention relates to im'provements in pipe couplings. to The objectof the present invention is to provide a simple, inexpensive, andefficient coupling for hose and other flexible tubing, to enable hose tobe readily and securely attached to the sections of the coupling, and toI5 facilitate rapid connection and detachmentl of the coupling sections.

Theinvention consists in the construction and novel combination andarrangement of parts hereinafter fully described, illustrated zo in theaccompanying drawings and pointed out in the claims hereto appended.

In the drawings-Figurel is a perspective view of a coupling embodyingthe invention. Fig. 2 is a longitudinal sectional View.

z 5 Like numerals of reference indicate corresponding parts in both thefigures of the drawings.

l and 2 designate cylindrical telescoping Y coupling sections; theinnersection is pro- 3o vided with diametrically disposed lugs 3; and theouter section 2 is provided with bayonet ways 4 to receive the lugs 3.Each bayonet way consists of a longitudinally disposed groove 5, formedby bending the metal out- 3 5 ward, and an inclined or angularlydisposed slot 6 forming a wedge, adapted when the sections are turned todraw them together. The inner section lis provided at its outer end witha cylindrical lining 7, which re- 4o ceives a piece of hose 8, and whichis arranged adjacent to the inner section 1. The outer section isprovided with a cylindrical lining 9, which receives a piece of hose 10,and which is ot less diameter than the outer section 2 to form anannular space between it and the outer section to receive the innersection when the sections are telescoped, in order to bring the adjacentends of the hose together. The linings 7 and 9 are se- 5o cured to theirrespective sections l and 2 by soldering, brazing,'or other suitablemeans. Each piece of hose is iirmly and securely fastened within thesection to which it is applied by a tapering wedging sleeve ll, whichcompresses the hose against the lining receiving it. The outer end ofthe outer section 2 is reduced and secured to its lining in order toform the annular space for receiving the inner se'ction l. z

It will be readily seen that the coupling is 6o inexpensive inconstruction and possesses great simplicity, that itis capable ofAenabling hose to be readily coupled and uncoupled, and that the parts ofthe hose are securely fasi tened within the sections of the coupling.

Changes in the form, proportion and the minor details of constructionmay be resorted to without departing from the principle or sacrificingany of the advantages of this invention. 7o

1. In a coupling, the combination of telescoping sections, means forsecuring the sections together, a cylindrical lining arranged within theouter section and secured thereto at the inner end thereof and formingbetween it and the outer section an annular space receiving the innersection, iiexible tubing arranged Within the inner section and thecylindrical lining of the outer section, and the 8o taperingwedgingsleeves clamping the flexible tubing in place, substantially asdescribed.

v2. In a coupling, the combination of an outer section provided withbayonet ways composed of longitudinal grooves and inclined slots, aninner telescoping section iitting within the outer section and providedwith lugs to engage the bayonet Ways, the linings arranged at the outerends of the sections, the lining of the outer section being of lessdiam- 9o eter than its section and forming an intervening spacereceiving the inner section, flexible tubing arranged within thelinings, and the tapering wedging sleeves fitted within the Iiexibletubing and compressing the same against the linings, substantially asdescribed.

In testimony1 that I claim the foregoing as my own I have hereto affixedmy signature in the presence of two witnesses.

BENJAMIN FRANKLIN STONE.
